Which motor is used in AC compressor?
Permanent Split Capacitor (PSC) electric motors have many HVAC applications. They are used for many refrigeration and air conditioning compressor applications. These motors, are single phase electric motors.
Which type of motor is used in air conditioner fan?
Operating principles. The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.
Is idling bad for engine?
Ten seconds of idling can burn more fuel than turning off and restarting the engine. Plus, excessive idling can damage your engine’s components, including spark plugs, cylinders and exhaust systems. Fact is, it has little impact on engine components like your battery and starter motor.

What causes rough idle when AC is on?
The symptoms are consistent with deposits in the throttle body. There are other potential causes. These deposits accrue in the intake manifold over time. They build faster with short trips and low quality fuels. Inspection and cleaning of the throttle body would be first thing to look at for this symptom.
Where are the coil packs on a Volvo 960?
Remove spark plug access cover. (Black cover on top of engine.) Once you have the black plastic cover off, number the coil packs with a magic marker 1 – 6 front to back so you can correctly replace them. Coil packs are held in with a pair of 10mm bolts (A and B in the illustration.
What are the symptoms of a rough idle engine?
It is possible for you to test the EGR valve at home, using a hand held vacuum pump. Other symptoms: An EGR stuck open may include a rough idle, rough performance at low engine speeds, stalling at idle, increase in fuel consumption, fuel odors, and possibly a check engine light on. 4. MAF Sensor
